Take a look at https://hazelcast.com/partner/jhipster/
You will find a link to a sample JHipster app that uses Hazelcast as Hibernate L2 cache, web session clustering etc.

I have a problem with Spring Boot application. I want to connect a Firestore and a MySql database in my Spring boot application. I would to know if it is possible. So I'm wondering if someone have an easy example to know this magic. Thanks.
Connection itself shouldn't be any problem. Firestore has well developed API for all popular languages, very simple and convenient to use, please check reference bellow.
You have mentioned MySQL, not sure if you are aware that GCP has also serverless Cloud SQL that can run MySQL for you (documentation).
You can find it here references and quick-starts here:
Google Cloud Firestore: quickstart, How-to and API reference.
Here I found example app tutorial: youtube.
Other interesting stuff: Spring Boot on GCP, Deploying on cloud from docs.spring.io.
You can also deploy your Spring Boot app on App Engine which can give you serverless solution for whole your stack - whole on GCP.
I am new in liferay want to perform crud operation using service builder so i want to understand need & use of apache felix web console bundle in liferay 7.1 so that i use it in order to check json/webservice api.
I would say you are not looking at the right tool for the job.
The console enables you to interact with the OSGi framework, a good place to start is not on the console but on the file systems if you are looking into understanding how Liferay uses the framework. The framework is embedded into the web app in order to provide the environment where bundles can live and provide services collectively.
Gogo is an auxiliary tool that enables interaction, you can query if bundles are installed, check the dependencies that you missed and who is providing a certain service or exposing a package.
Most of day-to-day of this kind of information you can also find in the app manager and/or logs.
About testing you api, I assume you are looking for seeing if it was installed and if it was resolved and activated. The app managers can provide the first clue for this, but gogo is an adequate tool as well, you will need to learn its commands and syntax. Do not worry they are trivial, you can find a description on the Apache's project page an on Liferay's dev guide.
Now, if you are looking to test the API for correctives or availability, using gogo will demand custom commands and lots of extra logic other tools provide for you.
I'm trying to learn how to build a restful webservice with Spring on tomcat external server but I'm only able to find guides that use spring-boot. I'd like to fully understand all the lifecycle, is there anyone who can help me to build a simple rest webservice from the scratch?
Are you offline when you do google search? :) just search the term "Spring Rest" see -> Spring Rest
And the first 10-20 results are all Spring boot and Rest guides.
yes with the help of spring boot to develop API is very easy. there is not any configuration required. for details please find the below post and I hope you will get answer of all your query.

I am looking to implement ElastiCache(using memcached) for my spring application. From here I can see that this can be done using spring cloud aws, but I could not find proper steps for doing this anywhere. Can anyone please provide some example implementation or tutorials?
Take a look at Simple Spring Memcached (SSM) project. It provides integration with AWS Elasticache through custom annotations or Spring Cache Abstraction.
I am working in windows 7 machine.I want to implement search using apache solr with hbase ta
bles as datasource. I have configured apache solr 4.3.1 in tomcat 7. I can able to deploy it successfully by manually starting tomcat server.
When i try to start solr server from within spring mvc web application it says solrserver started,but when i query the solr its giving the following without any errors:
page 0 of 0 containing UNKNOWN instances
As per my research on solr, it is mentioned embedded solrserver is unfit for production so i need to have httpsolrserver.
So somebody help me clear my head and give me some solution...
Thanks in advance..
For production, you would be better with hosting Solr as a seperate instance.
This would keep the responsibility separate, web application and search engine.
Indexing process are resource intensive and would the web application behavior as well.
This can be catered by Master Slave arch, providing best search performance.
External instance can be scaled at will and would not impact the web application.
